The walk is to remember the victims of the Sept. 11 terrorist attacks and to honor U.S. military personnel. A short program will be held starting at 5 p.m. before the walk. It will include J.R. Martinez, an Army veteran wounded in Iraq who is now an actor on "All My Children." Also on the program will be Bonnie Carroll, who lost her husband in an Air Force plane crash and founded the Tragedy Assistance Program for Survivors.

After the program, participants can join a 1.8-mile walk to begin in the Reagan Library courtyard and conclude at Rancho Madera Community Park off Wood Ranch Parkway.

Free shuttle service will return participants to their cars at the library. The first 1,000 people who register will receive a free Freedom Walk T-shirt and an American flag.
